Electronics project... I need Help!?

Question

Hi I Need to hand over a project for my final year. Im doing a doorbell for the Deaf. Instead of a sound alert a LED will light up indicating that there's someone at the door. But the schemetic Diagram I have got from the net is connected with Wire. But I want to improvise it by Making it wireless. What my lecturer suggested was to join a RF transmitter n Receiver To make it wireless. But I find it very complicating. Any idea Where do I get a infared Transmitter & Receiver Circuit diagram? How do I connect to my doorbell Circuit? PLease help... Thank You!

Answer 1

You may find an RF transmitter/receiver electronics kit at Radio Shack. You may find infra-red transmitter/receiver kits also. Do a google search on RF transceivers. A good source for things like this is DigiKey http://www.digikey.com/
